干式除尘装置在余吾煤业的应用与改进

Application and Improvement of Dry-type Dust Removal Unit in Yuwu Coal Mine

为进一步降低掘进工作面的粉尘浓度,余吾煤业引进干式除尘装置。针对使用过程中存在的问题,通过优化除尘装置安装方式,采用悬挂安装方式,实现随掘进工作面同步移动;通过对负压风筒进行加固优化,解决了负压风筒出现变形、吸瘪问题。干式除尘装置工作时,综掘工作面全尘和呼尘的除尘效率均在93%以上,除尘效率较高。综掘工作面作业环境明显改善,对现场作业人员身体健康大有帮助。

In order to the dust concentration of the driving face,the dry-type dust removal unit is introduced to Yuwu coal mine.Aiming at the problems in the using process,some measures are taken,such as the suspension installation to achieve simultaneous movement with the driving face,reinforce the fan drum to solve the deformation problem of the fan drum.When the dry dust removal unit is working,the dust removal rate in the driving face is above 93%.The working environment has been significantly improved,which is very helpful for the health of the field workers.
